Title: Video-signal processing device and selective noise-attenuation device in said device
Inventor: HAKU TOUTETSU
IPC: H04N5/21
Filed: 1991-07-01
Abstract: PURPOSE: To automatically control noise attenuation to stabilize the picture quality by selecting whether the noise attenuation processing should be executed or not based on lightness information in a video signal. CONSTITUTION: A Y signal inputted to an input end 1H is simultaneously inputted to a noise attenuation processor 20, a buffer part 40, and an averaging part 50 through a level limiting part 10. The averaging part 50 consists of an integrating circuit and outputs the value of lightness of the Y signal. A comparison part 60 compares the inputted value of lightness with an internal reference value and outputs the comparison result. A switch selecting part 70 controls a switch part 30 in accordance with the comparison result to output the output to an output out 2H through the processor 20 or the buffer part 40. The switch part 30 may be selected by a user selection part 80. Thus, noise is automatically attenuated in accordance with the state of the video signal.

Title: Data-reproducing apparatus
Inventor: JINGU YASUYUKI
IPC: G11B20/18
Filed: 1999-06-08
Abstract: PROBLEM TO BE SOLVED: To lower the data non-reproducible ratio after retrial by overwriting for every byte data an ECC block on a memory for only byte data judged to include no error from error detection information outputted to data not fulfilling a demodulation rule at retrial. SOLUTION: A demodulation circuit 81 converts 16-bit data from an A/D conversion circuit 4 in to byte data on the basis of an EFMPlus modulation rule. An this time, 16-bit data not fulfilling the rule are made optional byte data and outputted with an error detection signal to an EMIF 84. The EMIF 84 stores the byte data into a RAM 85. An ECC circuit 83 corrects error to an ECC block on the RAM 85. If the error correction is impossible, a microcomputer 7 makes a servo circuit 6 read out a necessary ECC block again from an optical disk 1. At this time, the EMIF 84 overwrites and updates the ECC block for every byte with reference to the error detection signal from the modulation circuit 81.

IPC: G11C11/401
Filed: 1989-06-23
Abstract: PURPOSE:To reduce a through current and power consumption and to easily perform inversion transfer by providing load elements at common power source wiring and ground wiring in an array. CONSTITUTION:Data transfer are performed in (m) second memory cells 7-1,..., 7-m since first and second MOS transistors 13-1, 14-1..., 13-m, and 14-m are turned on simultaneously, however, assuming that m' second memory cells in which the inversion transfer are performed exist, a current of m' times intends to flow on a load resistor 16, therefore, the potential of the ground wiring 9 rises remarkably. Similarly, the potential of the power source wiring in the array is decreased remarkably less than a power source level by a load resistor 15. Therefore, potential difference between the source and gate and between the source and drain of each of an Nch TR 30, an Nch TR 31, a Pch TR 32, and Pch TR 33 is decreased, which makes it hard to turn on. Therefore, the through current that flows from the common power source wiring 5 to the ground via the load resistors 15 and 16 can be suppressed.
